The fatigue life and fatigue limit of commercially pure Ti grade 2 and 4 in coarse-grained and ultrafine-grained
states were experimentally determined. Ultrafine structures were prepared by Conform severe plastic deforma tion method and by conventional Equal channel angular pressing, respectively. The differences in the
improvement of fatigue life and the influence of both procedures on the fatigue limit based on 107 cycles to
fracture are discussed in terms of grain refinement, microstructure, differences in fatigue damage mechanism and
influence of surface roughness on the initiation of fatigue cracks. Improvement in fatigue life was observed for
both materials, however, the improvement of the fatigue limit was found only for Ti grade 2.
